Washington ( CNN ) -- While Jeb Bush is still publicly noncommittal about a possible presidential bid , his family is far less circumspect . And if recent comments by George P. Bush are any indication , Jeb Bush 's eldest son got the go-ahead from the family . The bigger question , of course , is whether Jeb Bush got the go-ahead -- from himself . While George P. told ABC that `` I think it 's more than likely that he 's giving this a serious thought in moving forward , '' it 's still unclear whether his father is actually willing to dive into a presidential bid . One source with knowledge of Jeb Bush 's thinking tells CNN `` wanting to do this and doing it are two different things . '' In fact this source adds , `` He has n't made a decision yet despite reports to the contrary . He is seriously considering and is going through a thoughtful process . He appreciates the warm wishes and support , but he is a methodical guy and wo n't change his timeline . '' That timeline anticipates Jeb Bush making a decision by the end of the year . While some donors may be waiting to see what Bush does before they commit to a candidate , the source says Bush himself has not asked for them to stay on the sidelines . `` They are calling him , but all he is saying is he has n't made a decision . There is no organized outreach sanctioned by him . '' Several donors told CNN that that in private sessions , Bush has not given any more indication than he has publicly about his intentions . One of the donors said `` he is behaving as if he is looking at it seriously , '' but his reluctance to talk about it is `` wearing thin . '' The choice about whether to run , a source close to Bush explains is `` a serious decision which he understands better than most . '' OPINION : Six Senate races to watch . With a brother and a father who have served in the highest office , that 's a fact . But it 's clear both of them -- Bush 41 and Bush 43 -- would like to him to run . `` If you asked Dad the same question -- 'Should Jeb run ? ' -- he 'd say yes , '' Neil Bush said in an interview with CNN earlier this year . `` Yeah , he would say yeah . '' Former President George W. Bush told Fox News earlier this month he had encouraged his brother to run . `` He and I did have a conversation . I of course was pushing him to run for president . He of course was saying , ' I have n't made up my mind , ' '' Bush said . `` He 's seen his dad , he 's seen his brother . And so he 's a very thoughtful man and he 's -- he 's weighing his options . '' One person who has not been enthusiastic about a possible Jeb Bush run has been his mother , Barbara Bush , who had told interviewers there were `` enough Bushes '' who had been President . However , Jeb told the AP that she was now `` neutral , trending in a different direction . '' The notion of Jeb Bush running is something that has resurfaced after years of dormancy . `` If you had asked me a few years back , I would 've said it was less likely , '' George P. Bush , who is running for Texas Land Commissioner , told ABC . `` The family will be behind him 100 % if he decides to do it . '' WATCH : Are fear politics dominating the midterms ? One calculation that seems to have changed recently is Bush 's closest family support . He told the Associated Press earlier this month that his wife , Columba , is `` supportive '' of a possible run for the presidency . Before his statement , many in political circles assumed she would be reluctant -- even a stumbling block- to engage in a presidential campaign . Bush has been active on the campaign trail during the midterm elections , stumping for GOP candidates across the country -- and helping them raise money . He 's clearly collected chits -- but then again , so have all of the potential Republican 2016 contenders .
Bush son told Texas Land Commissioner that `` it 's more than likely '' that Bush is giving the end of the year run `` serious thought '' Bush is expected to make a decision by 2016 . Jeb Bush 's is n't giving any public indications of his thinking .
