Counting down to the final votes on his health care legislation, President Barack Obama says the only question left to answer is: Will the country let the insurance companies win again?

Rallying support at a campaign-style rally in northern Virginia Friday, Obama said the insurance industry will continue to "run wild" if the House vote set for Sunday fails.

Republicans are united in opposition to Obama's proposal, and House Democrats are still searching for the 216 votes they need to pass the Senate version of the sweeping overhaul bill and send it to the president for his signature.

Without change, Obama says insurance companies will continue to deny people coverage and care and impose stiff premium hikes.

Several thousand supporters of health care reform are gathering at George Mason University for the rally.

The rally at the school in Fairfax Friday is in the congressional district of Rep. Gerry Connolly, a freshman Democrat who has not yet decided whether to support the House health care bill. A vote is expected this weekend.

Outside the arena, several hundred opponents protested the rally. They were joined by the two Republicans seeking to unseat Connolly.

Connolly did not attend the rally.
