Rick Santorum says he expects to do well in the next GOP presidential contests and will be in a two-man race with Mitt Romney.
Santorum is coming off victories last week in Colorado, Minnesota and Missouri, and says he can have good showings Feb. 28 in Michigan and Arizona.
The former Pennsylvania senator says he’s the latest candidate to challenge front-running Romney and he says Romney is having trouble figuring how to go after a rival who is a “solid conservative’’ with the ability to win support from independents and Democrats.
