PHOENIX — Rep. Martha McSally is leaning on Republican interlopers across the GOP spectrum in a last-minute scramble to put her over the top on Tuesday in a seat the party is desperate to hold onto.

In the waning days of the election campaign, McSally has welcomed a host of Republicans from all factions of the party to the Sun Valley as part of her push against Rep. Kyrsten Sinema, D-Ariz., on Tuesday.
