With just a week to go before the Iowa caucus, several Republican presidential candidates are making a last minute push for votes.
On Tuesday, Rep. Michele Bachmann, R-Minn., Texas Gov. Rick Perry, and former House Speaker Newt Gingrich are hitting the road with bus tours across the state.
Each one is fighting to prove to voters that they are a more conservative alternative to former Mass. Gov. Mitt Romney.
But some analysts say even with the efforts of candidates like Bachmann and Perry with just seven days left, the race will be between Romney, Gingrich, and Rep. Ron Paul, R-Texas.
"There's really three primaries going on here," former Sen. Rick Santorum of Pennsylvania told reporters in Adel, where he went hunting for pheasant and quail.
"There's the Libertarian primary, which Ron Paul is going to win. Then you've got the moderate primary, which Gingrich and Romney are scrumming for. And you've got three folks who are running as strong conservatives," Santorum said, including himself with Bachmann and Perry among the conservatives.
Still, recent polls show that many Iowa Republicans remain undecided.
