LAKE JACKSON, Texas (AP) -- Where's Ron Paul?
The Republican presidential candidate has spent most of the past week at home in Texas rather than on the campaign trail.
His decision isn't likely to quiet speculation that he's not really in the race to win.
Polls show that Paul is in the thick of the competition in next Saturday's South Carolina primary. He finished in the top three in Iowa and New Hampshire this month.
But his absence from the trail this past week and earlier comments suggesting he didn't expect to occupy the White House have led to suggestions that his race is mostly about drawing attention to his libertarian ideas, such as eliminating the Federal Reserve.
Paul has dismissed such speculation. He says his strategy is working and his momentum is building.
