-Mitt Romney is on hiatus from the trail, opting instead to spend Tuesday in Denver, preparing for tomorrow's debate (the first of three, the debate kicks off at 9:00 EST and will focus on domestic policy).

-Speaking of Colorado, a swing state whose large Latino population could be the decisive difference, Romney clarified his stance on the Obama administration's new policy shielding young undocumented immigrants from deportation. Romney has so far deflected questions about whether he would honor the program if elected, but on Tuesday he told the Denver Post that a reprieve "would continue to be valid" for immigrants who had been granted it.

-Paul Ryan will be in Iowa, continuing on the latest iteration of the Romney-Ryan bus tour (last week it was Ohio). Ryan will be stopping in the towns of Clinton, Muscatine and Burlington.

-Ryan slammed Obama on foreign policy last night, citing Libya as an example of how the president's foreign policy is "unraveling before our eyes." (The foreign policy debate is on Monday, Oct. 22; the Oct. 16 debate will be town hall-style and will include some foreign policy questions as well.)

-American Crossroads and Crossroads GPS, the conservative advocacy organization/Super PAC spearheaded by Karl Rove, is launching a $16 million, one-week ad campaign faulting Obama for a stubbornly high unemployment rate.
