The New York Times reported the breaking news yesterday.
Mr. Carson has amassed considerable new support from Republican primary and caucus voters and is now running nearly even with Mr. Trump as their pick for the party’s presidential nomination, according to a new New York Times/CBS News poll.
Carson increased from 6% to 23%. Trump's standing moved a little from 24% to 27%. Fiorina moved up from essentially zero to 4%.
Maybe the bigger story is who lost. Bush dropped from 13% to 6% and Walker dropped from 10% to 2%.
It's hard to determine cause and effect in this game but here are a couple of possibilities about Walker's drop. (1) The GOP voters are not resonating to his constant picking on labor. (2) He knew he was not doing well with his party's base so he increased his promises to get rid of unions. Whatever. Both Bush and Walker campaigns are not firing up their base.
