There are many hotly disputed races projected for the 2010 midterm elections.
One of the most heated primaries is in California.
It consists of three Republican candidates for a seat in the U.
S.
Senate.
The election that will give one of them the Republican nomination is set for June.
The most well-known contender is Carly Fiorina, former CEO of computer company Hewlett-Packard, but that does not mean she is a lock.
State Assemblyman Chuck DeVore and former Representative Tom Campbell are also in the hunt.
Obviously, healthcare reform is one of the major issues for their campaigns.
Above all, each candidate wants to repeal the national law due to its purported unconstitutionality--a common GOP view.
Their opposition is essential for winning over primary voters, who generally tend to be more partisan than general election voters.
However, they also need to distinguish their campaigns.
While "repeal and replace" is a shared strategy, each candidate has their own proposals for what the Obama administration's legislation should be replaced with.
What do they want to do?

• Fiorina has extensive business experience, which she is planning to use to create a more commerce-friendly law that will result in less of a burden on the state's budget.
  She wants to create new high-risk health insurance pools for people with pre-existing conditions, a measure included in the current bill.
  Medical malpractice tort reform is an essential part of her proposal, as is buying health insurance across state lines.
  Several of her proposals are taken from John McCain's 2008 presidential campaign, which she worked for.
  In addition, she promotes greater utilization of existing programs for the poor, and supports the more widespread use of cost-effective community health clinics.
  Having the government get in the game by subsidizing coverage would be a last resort.
  
• DeVore agrees with many of Fiorina's proposals, as well as her assertion that the current law will eventually bankrupt California health insurance providers.
  However, he would like to expand the use of tax credits.
  His tax credit would be equal to the cost of a catastrophic high-deductible health insurance plan.
  
• Campbell, as expected, is in favor of several of the aforementioned GOP proposals.
  He also has some unique ideas, such as having health insurers bid for a limited amount of government subsidies for people who are poor or suffering from pre-existing conditions.
  It is an interesting take on the contract bidding process often used for military purchases.
  Campbell is the only California Republican primary candidate who has not signed a pledge to repeal the Democratic-led law; he says that is because he wants to be for something else, as opposed to simply against "Obamacare".
  

For the most part, California continues to be a heavily Democratic state.
It is one of the few in which affordable health insurance reform maintains majority support in the polls.
Therefore, the eventual Republican candidate will struggle to win over moderates against Democrat Barbara Boxer in November.
