INDIANAPOLIS (AP) — A Republican challenger to President Donald Trump and at least eight Democratic presidential candidates are poised to join Indiana’s May primary.

Figures provided Friday by the Indiana secretary of state’s office show the campaigns for Trump and former Massachusetts Gov. William Weld have collected enough petition signatures to qualify for the Republican ballot.

The Democratic primary ballot could be crowded, with former South Bend Mayor Pete Buttigieg among those apparently meeting Indiana’s requirement of 500 voter signatures in each of its nine congressional districts.

Others tare Joe Biden, Amy Klobuchar, Bernie Sanders, Elizabeth Warren, Michael Bloomberg , Tom Steyer and Andrew Yang. Tulsi Gabbard is close to qualifying.
