I'm not sure what data you're seeing, but I would be careful before counting your chickens before they hatch.
A recent Gallup poll suggests that more people consider themselves to be conservative now than in recent past. I tried Googling it, and came up with this link, so try not to criticize the source, since it was posted elsewhere. The poll was from Gallup, which I thought was a good source during the election.
In 2009, 40% percent of respondents in Gallup surveys that have interviewed more than 160,000 Americans have said that they are either “conservative” (31%) or “very conservative” (9%). That is the highest percentage in any year since 2004.
Only 21% have told Gallup they are liberal, including 16% who say they are “liberal” and 5% who say they are “very liberal.”
Thirty-five percent of Americans say they are moderate.
During Republican President George W. Bush’s second term, the number of self-identified conservatives as measured by Gallup dropped, riding at a low of 37% as recently as last year.
According to new data released by Gallup on Friday, conservatives outnumber liberals in all 50 states--including President Obama’s home state of Illinois--even though Democrats have a significant advantage over Republicans in party identification in 30 states.
