Democratic presidential candidate Barack Obama, criticized by his Republican rival because of his support for a timetable to withdraw combat forces from Iraq, leads among all candidates in donations from U.S. servicemembers overseas, according to a new report based on government data.

The non-partisan Center for Responsive Politics, drawing on Federal Election Commission filings, said Democrat Obama has received nearly six times as much money from troops deployed overseas at the time of their contributions than has McCain.

Republican Ron Paul, who has suspended his campaign, received more than four times McCain's donations, CRP said.

The data stand in contrast to the 2000 and 2004 election cycles, when Republican George W. Bush raised more money from the military than his Democratic rivals, Vice President Al Gore and Sen. John Kerry, CRP said.

Here are the amounts and numbers of contributions ranked from troops deployed abroad, based on contributions made during the 2008 election cycle through June 31, 2008.

1 Obama $60,642 (134)
2 Paul $45,512 (99)
