DES MOINES, Iowa (AP) -- Republican presidential candidate Ron Paul returned to Iowa the day before its lead-off presidential caucuses, hoping to rev up supporters by appearing with his son, U.S. Sen. Rand Paul of Kentucky.
The older Paul, a Texas congressman near the top in recent Iowa polls, stepped off the campaign trail for the New Year's holiday and had returned home.
The father-son team began a five-city swing by charter jet in Des Moines Monday.
A weekend poll showed Paul narrowly trailing leader Mitt Romney, though Paul's support had ebbed somewhat, as his rivals sharply criticized his foreign policy positions.
