Talk about crashing a party. 

Milton Mayor Joe Lockwood has endorsed all three Milton city council incumbents up for re-election, including Tina D'Aversa, Bill Lusk and Karen Thurman.

Showing his grace, Lockwood hosted a fundraiser for D'Aversa at his home on Sunday night.

Attendees say it was sparsely attended, with mostly Julie Zahner-Bailey supporters.

But Lockwood got some of his key donors to come out and help D'Aversa.

So how does D'Aversa show her gratitude?

By inviting the opponents of Lusk and Thurman to the fundraiser, Alex Trevillyan and Bernard Wolff, letting them speak, and endorsing their candidacies.

Right in Lockwood's living room, nonetheless.

LOCKWOOD SUPPORTERS WALK OUT

Several attendees at the event, aghast at D'Aversa's contrivance, walked out in disgust.  Sources say that one notable contributor asked for his donation check back. Another told us he was putting a stop payment on his check to D'Aversa.

Lockwood, showing his class, simply went outside when the D'Aversa sell-out got underway.

This now confirms what we predicted last week: D'Aversa has no choice but to throw in with Zahner-Bailey.

Lockwood is stuck with her, as his loyalty is one of his trademarks.

But the races have changed, regardless of whom Lockwood publicly supports.

The November 3 Milton election has now morphed into two diametrically and philosophically opposed slates: Lusk, Thurman and Longoria, who side with Councilman Burt Hewitt and Lockwood on most policies VS. Trevillyan, Wolff and D'Aversa, who side with Zahner-Bailey and Councilman Alan Tart.

If Zahner-Bailey sweeps the board, she controls the Milton City Council.

If her three candidates get thumped, she becomes irrelevant, stuck with Tart in a perpetual two-vote naysayer minority.

The Milton Council election is no longer Julie VS. Joe.

It's now become Julie VS. No Julie.

If Zahner-Bailey pulls this off, Lockwood will be wondering where he went wrong.

He can start with his ill-fated politically expedient endorsement of D'Aversa.

Be careful what you wish for, Joe.
