Clinton camp preparing for possibility Trump won't concede

WHITE PLAINS, N.Y. (AP) — Hillary Clinton's campaign is increasingly preparing for the possibility that Donald Trump may never concede the presidential election should she win, a development that could enormously complicate the crucial early weeks of her preparations to take office.

Aiming to undermine any argument the Republican nominee may make about a "rigged" election, she hopes to roll up a large electoral vote margin in next month's election.

Clinton's team is also keeping a close eye on statements by national Republican leaders, predicting they could play an important role in how Trump's accusations of electoral fraud might be perceived.

While Clinton's campaign has long focused on maintaining pathways to cross the threshold of 270 electoral votes, it's now looking to capture an expanded number of states that could also help determine control of the Senate — including Republican-leaning Arizona.

Clinton's campaign is making a significant push in Arizona, which offers 11 electoral votes and has stayed in the Republican column in all but one presidential election since 1952.

First lady Michelle Obama courted voters in Phoenix on Thursday, following appearances by Vermont Sen. Bernie Sanders and the Clintons' daughter, Chelsea Clinton.

[...] many of the state's Republicans have abandoned Trump and polls show Clinton and Trump in a tight contest against independent Evan McMullin, a conservative former CIA officer who graduated from Brigham Young University.
