(CNN) - Mitt Romney is back on the trail after spending Wednesday in Boston. He will begin a Western campaign swing, starting in Colorado Thursday and Nevada Friday. After an event in Golden, Romney will join Republican governors - many of whom are rumored to be on the presumptive GOP nominee's shortlist for a vice presidential pick - at a roundtable discussion in Basalt, Colorado. Romney will then attend a fund-raiser in Aspen where he will be joined by New Jersey Gov. Chris Christie.
Following his Wednesday trip to the battleground of Ohio, President Barack Obama will campaign in the toss-up states of Florida and Virginia Thursday. Meanwhile, wife Michelle Obama will rally supporters in New Hampshire.
