Armed with devoted grassroots support, Representative Ron Paul, R-Texas, launched a dynamic conservative movement along with his 2008 presidential bid. He lost the GOP nomination, but Paul is hosting a rally, the Campaign for Liberty's Rally of the Republic, in Minneapolis, opposite the official Republican National Convention.
In the 2012 election, the Republican primary contest has shifted to Illinois. It's the latest state where voters are trying to choose from among the four, remaining mainstream Republican candidates, including Mitt Romney, Rick Santorum, Newt Gingrich and Ron Paul.
Mitt Romney needed convincing victories Tuesday to cement his status as the front-runner — and he got them. With big wins in Maryland and Washington, D.C., and a big enough victory in Wisconsin, the other Republicans still in the race will have a hard time convincing voters and donors they remain relevant.
