WASHINGTON (AP) -- Former House Speaker Newt Gingrich said Monday there is a very good chance he'll get into the race for the 2008 Republican presidential nomination, but he won't decide until after September.

"I think right now that it is a great possibility," Gingrich said. "I don't want to get into all this stuff. I want to focus on what we have to do to make America successful."

Gingrich said he plans to hold a workshop on solutions facing the country in September, after which he'll make a decision on whether to launch a presidential bid.

He made the comments Monday on ABC's "Good Morning America."

Gingrich left Congress when Republicans lost seats in the 1998 elections after a campaign that highlighted then-President Clinton's affair with Monica Lewinsky.

Asked about former first lady and Democratic front-runner Hillary Rodham Clinton's White House prospects, Gingrich said:

"I think she has a very good chance of winning the presidency... I think unless Republicans are as committed to very fundamental change in Washington that they will almost certainly lose the election."
