ABINGTON, Mass. (AP) — Former U.S. Attorney Michael Sullivan says he has enough signatures to be on the Republican ballot for U.S. Senate in Massachusetts.

Sullivan delivered a batch of signatures to Abington Town Hall on Wednesday and said he had between 23,000 and 27,000. He needs 10,000 certified signatures to be placed on the primary ballot.

Sullivan said he was excited to submit that many signatures after starting his all-volunteer signature-gathering effort 12 days ago. Sullivan said his volunteers' ability to gather so many signatures in less than two weeks shows he has a "groundswell of support."

Sullivan has two opponents in the Republican primary, former Navy SEAL Gabriel Gomez and state Rep. Dan Winslow.

Sullivan says he is anti-abortion and fiscally conservative. He says Washington is broken and people need to use common sense to reach agreement.
