( CNN ) -- While there is still a lot of talk about how the Republican Party needs to reinvent itself , Democrats should keep in mind they could use a touch-up themselves . With 20 Senate seats to defend in the midterm election -- compared with just 13 Republican ones -- the truth is Sen. Harry Reid and the gang do not have a lot of time to gloat . The economy may be improving , but it is still limping ; millions are looking for work , and the deficit continues to grow . So whatever momentum President Obama and the Democrats received from last week 's victories will all be gone come 2016 if they ca n't agree on a detailed budget plan by 2014 . And let 's be clear : Taxing the rich and closing some loopholes is not a detailed plan . Granted , Democrats are proposing spending cuts -- but they have to be more bullish about their proposed cuts than they are about taxing the rich . The latter got them elected but the economy is in more need of the former . Allowing the Bush tax cuts to expire for those who make $ 1 million a year or more , as championed by some , is estimated to generate only $ 500 billion to $ 600 billion over 10 years . That dwarfs the number cutting off Big Bird would bring but it does little to solve the debt problem . Opinion : Conservatives , do n't despair . So any plan that does not include significant spending cuts is no plan at all . If Democrats want to build on last week , they have to be bold , because they ca n't depend on Republicans to say stupid things about rape or ignore minorities forever . In fact , confetti was still falling in Chicago when George P. Bush -- the Spanish speaking , half-Mexican nephew of you know who -- filed his papers with the Texas Ethics Commission to run for an as-yet unspecified office . The 36-year-old is the co-founder of the political action committee , Hispanic Republicans of Texas . That alone wo n't solve all of the party 's image problems with Latinos , but as long as he 's not on the crazy , inflammatory side of his party , he 's got the looks , charisma and name to be the kind of political star they need -- the kind who can draw big crowds and maybe sway Latino voters two years from now , if not for himself , then certainly for another GOP candidate . Face it Democrats -- the celebration is over and it 's time to get to work . At least six of the Senate seats the party has to defend are in red states . Lose those , and President Obama could be spending his final two years butting heads with a Republican Congress . So what do the Democrats need to do ? Opinion : Election a call for purple politics . Well for starters , identify candidates to go after Maine Republican Sen. Susan Collins ' seat , because Obama won Maine . Second , be a party white people want to vote for . Lost in all of the hoopla about Republicans needing to adapt to the country 's new demographic , is the fact Romney captured the largest percentage of white votes since Ronald Reagan . True , some of that can be attributed to racist backlash to Obama -- but most of it has to do with the message of the Democratic platform . Romney characterized 47 % of the country as a bunch of moochers ( and coincidentally came away with 47.8 % of the popular vote ) . That means a lot of voters : the numbers suggest 88 % of the people who voted for Romney were white . That 's a problem . If Democrats do n't figure out a way to make their message attractive to white people , they could possibly lose the Senate . And third , and probably most important , they have to be a party worth voting for . One can certainly say Republicans , from the top of the ticket on down , shot themselves in the foot this election , making it easier for Democrats to paint them as a party to vote against . But for the 2014 midterm , Democrats must present a budget plan people want to vote for . In two years voters are going to be asking `` What else you got ? '' and if Democrats do n't have an answer , they risk getting shellacked in 2014 , the same way they got their butts handed to them in 2010 . Back then , Republicans took back the House . Politics : 2014 battle for the Senate starts now . Another GOP landslide could create a path to the White House . I hate to be the Ohio at your Karl Rove party , but it is what it is .
