Republicans are beginning to worry the bruising presidential primary may hurt their chances in some close Congressional races.

The Hill talks with some GOP house members who are worried that the long and drawn out race for the presidential nomination could hurt the party and their standing with voters.

Concerns about the prolonged primary calendar, with its proportional system of awarding delegates, were first reported earlier this month by The Hill. Top Republican National Committee members plan to reconsider the rules at the next committee meeting, slotted for late spring in Phoenix.

Not everyone expected the primary to go on this long. Some bold early predictions had Romney wrapping up the nomination by New Hampshire’s primary in early January. But Newt Gingrich and Rick Santorum have racked up enough victories to keep the race going, perhaps into May or June.

Rep. Trent Franks (R-Ariz.), a Gingrich supporter, said Super Tuesday proved Republicans are still not at peace with a Romney ticket, but acknowledged a protracted brawl could favor Obama. 

Romney supporters say Republicans who grumble about his inability to lock down the nomination early on have misplaced their frustration.
