I looked at IRS pub 501 and it sounds like you can choose which method you want to take. It says you SHOULD take....it doesn't say you HAVE to take the higher one.
IRS pub 501 page 22 says

Most taxpayers have a choice of either taking a Standard Deduction or itemizing their deductions. If you have a choice you can use the method that gives you the lower tax.
