"Issues have been raised," state Rep. Mark Hatfield, R-Waycross told Reality Check Radio last week (via Jim Galloway). "A lot of people are saying it's a political bill. So in order to allay concerns about the bill's potential political nature, I have proposed a substitute, which would move the effective date of this bill to July 1 of 2013."
Hatfield said the change was designed to show that the bill isn't targeted at President Obama -- even though the whole issue has been pushed for years now by people who believe Obama isn't eligible to be President, because they maintain he wasn't born in Hawaii. A number of Georgia lawmakers have removed their names from Hatfield's bill in recent weeks.
A similar bill proposed by New Hampshire Republicans, with a similar tweak making it go into effect in 2013, died in committee last week.
