A Nebraska senator has received hundreds of e-mails criticizing his vote in favor of the national health care reform bill.

Except he wasn't even in Washington when the vote was taken last month.

State Sen. John Nelson of Omaha says people have been confusing him with U.S. Sen. Ben Nelson, the Nebraska Democrat, ever since Ben Nelson cast a key vote last month to advance the reform package.

For the record, John Nelson disagrees with Ben Nelson's vote but says he doesn't envy the "intense pressure" the U.S. senator has received from both sides.

As for the confusion, John Nelson says he's discovered that many people don't know who their state or U.S. senators are, but at least they're interested in issues of the day.
