Skipping GOP convention?

Senators Susan Collins of Maine and John Sununu of New Hampshire are reportedly among the most vulnerable Republicans who could skip the national convention in St. Paul, Minn., where John McCain will be nominated as their standard-bearer -- the latest sign of skittishness among Republicans that this could be a Democratic year.

The National Journal reports online today that Collins has decided to spend convention week in early September campaigning in Maine instead. Her Democratic opponent, Representative Tom Allen, is enthusiastically going to Denver for Barack Obama's nomination, the magazine reports.

Sununu is still undecided whether to attend the GOP convention, National Journal says.

Most polls show that Democrats are in good position in congressional races, even in traditionally Republican states and districts, after Republicans lost a series of special elections this year.
