Poll: Bush Still Tops List of GOP Candidates, But Cruz Rising Fast

Former Florida Governor Jeb Bush continues to lead the pack of Republican presidential hopefuls, but one candidate is making moves. 

Texas Senator Ted Cruz, the only GOP hopeful to formally announced his candidacy thus far, has shot up in the rankings in a new CBS News poll. Thirty-seven percent of those surveyed said that they would consider voting for Cruz in March, up 14 points from when the same question was asked a month ago. 

By comparison, 51 percent said they would vote for Bush, just two percent higher than did in February. 

Still, while Cruz is enjoyed a one-month bump, the conservative Texan continues show serious weakness among Republican voters. Twenty-two percent of those surveyed said they could not vote for Cruz, one point higher than in February's poll. Twenty-seven percent of those polled said they could would not vote for Bush in March, while 26 percent said the same in February. 

Kentucky Senator Rand Paul also saw a significant jump over the past month, gaining nine points among those who said they would vote for him. 39 percent now say they could support Paul, while in February that number was just 30 percent. 

On the down slope, just 26 percent said they would vote for Ben Carson in March's poll, down eight points from when 34 percent surveyed said they would in February. 

While Bush's numbers seem relatively robust and stable, they don't quite hold a candle to frontrunner Hillary Clinton. For the second month in a row, 81 percent of Democrats surveyed said they would vote for Clinton.
