Nebraska's choice for the Democratic nominee for president was already determined in the caucuses in February, but with Hillary Clinton still giving Barack Obama a run for the money, it will be interesting to see what, if any, effect the May 13 primary might have.

Sample ballots are printed in today's edition, on pages 8-9, as well as a list of polling places and an application for early voting by mail. As the form notes, voters also may cast their ballots in the clerk's office through May 12.

While Nebraska may deliver little other than moral support to one of the Democratic presidential candidates, we will have a more difficult decision come fall.

Although all three leading candidates say they favor biofuels, Sen. John McCain is a reluctant supporter, and has said he opposes subsidies for ethanol.

As ethanol opponents raise more and more arguments against the fuel -- it increases food prices and may actually add greenhouse gasses to the atmosphere, they contend -- the health of the ethanol industry may depend on who occupies the White House.

Democratic and Republican Senate races are proving interesting, with advertising from Tony Raimondo and Scott Kleeb picking up. It will be interesting to see how Kleeb's personal charisma fares against Raimondo's business experience.

We do hope Amendment One passes muster this time around, since it should not be saddled with voter negativism about other issues that may have pulled it down last time it appeared on the ballot two years ago.

The amendment would allow cities to invest public endowment funds the same way a prudent investor would handle his or her own money.

Despite uncertain conditions of late, there's no reason, with careful, responsible management, endowment funds should not be able to benefit from exposure to the stock market.
