votes. Cheney and Biden were each chosen for their experience in national politics (experience lacked by both Bush and Obama) rather than the ideological balance or electoral vote advantage they would provide. The ultimate goal of vice presidential candidate selection is to help and not hurt the party's chances of getting elected; nonetheless, several vice presidential selections have been controversial. In 1984, Democratic presidential nominee Walter Mondale's groundbreaking choice of Geraldine Ferraro as his running mate (the first woman in U.S. history nominated for vice president by a major political party), became a drag on the ticket due to repeated questions about her husband's finances. A selection whose positive traits make the presidential candidate look less favorable in comparison or which can cause the presidential candidate's judgment to be questioned often backfire, such as in 1988 when Democratic candidate Michael Dukakis chose experienced Texas Senator Lloyd Bentsen; Bentsen was considered a more seasoned statesman in federal politics and somewhat overshadowed Dukakis. Questions about Dan Quayle's experience were raised in the 1988 presidential campaign of George H. W. Bush, but the Bush–Quayle ticket still won handily. James Stockdale, the choice of third-party candidate Ross Perot in 1992, was seen as unqualified by many and Stockdale had little preparation for the vice presidential debate, but the Perot–Stockdale ticket still won about 19% of the vote. In 2008, Republican John McCain chose Sarah Palin as his running mate over his primary rivals and/or campaign surrogates such as Mitt Romney, Tim Pawlenty or Tom Ridge. This surprise move would, it was hoped, draw women voters disappointed by Hillary Clinton's defeat in the Democratic presidential primaries into the McCain camp. Palin's selection soon came to be seen as a negative for McCain, due to her several controversies during her gubernatorial tenure which were highlighted by the press, and her feuding with McCain campaign chairman Steve Schmidt. This perception continued to grow throughout the campaign, especially after her interviews with Katie Couric led to concerns about her fitness for the presidency. Election The vice president is elected indirectly by the voters of each state and the District of Columbia through the Electoral College, a body of electors formed every four years for the sole purpose of electing the president and vice president to concurrent four-year terms. Each state is entitled to a number of electors equal to the size of its total delegation in both houses
