I'll be glad to take a look. Check this out from the Kaiser Commission

If all states implement the ACA Medicaid expansion, the federal government will fund the vast majority of increased Medicaid costs. The Medicaid expansion and other provisions of the ACA would lead stateMedicaid spending to increase by $76 billion over 2013-2022 (an increase of less than 3%), while federalMedicaid spending would increase by $952 billion (a 26% increase). Some states will reduce their ownMedicaid spending as they transition already covered populations to the ACA expansion. States with thelargest coverage gains will see relatively small increases in their own spending compared to increases infederal funds.If all states implement the expansion, gains in Medicaid coverage would substantially reduce the numberof uninsured. An estimated additional 21.3 million people would enroll in Medicaid by 2022, a 41% increasecompared to projected levels without the ACA. Most enrollees would be newly-eligible, but some would berelated to increased participation among people (primarily children) who are currently eligible. With theMedicaid expansion and other coverage provisions in ACA, the number of uninsured would be cut by 48%compared to without the ACA. However, even without the Medicaid expansion, Medicaid enrollment willincrease due to provisions in the ACA that will lead to increased participation among those currently eligiblefor but not enrolled in Medicaid and CHIP (including children). If no states expand Medicaid, Medicaidenrollment would rise by 5.7 million people, and the number of uninsured would drop by 28%.
The additional state cost of implementing the Medicaid expansion is small relative to total state Medicaid spending. The incremental cost to states of implementing the Medicaid expansion would be $8billion from 2013-2022, representing a 0.3% increase over what they would spend under the ACA withoutthe expansion. The $8 billion includes the state share of costs for both newly eligible adults and theadditional Medicaid participation among currently eligible populations that would result from expansion. Ifall states implemented the Medicaid expansion, federal spending would increase by $800 billion, or 21%,
,compared to the ACA with no states implementing the expansion.
Accounting for factors that reduce costs, states as a whole are likely to see net savings from the Medicaidexpansion. Combining Medicaid costs with a conservative estimate of $18 billion in state and local nonMedicaidsavings on uncompensated care, the Medicaid expansion would save states a total of $10 billionover 2013-2022, compared to the ACA without the expansion. Net state savings are likely to be evengreater because of other state fiscal gains that we could not estimate based on 50-state data.The following provides an overview of the cost and coverage impact of all states implementing the ACA.

Claims that states will bear a substantial share of the costs of expanding Medicaid, however, and that the expansion would drain state budgets do not hold up under scrutiny.
The Congressional Budget Office (CBO) estimates that the Medicaid expansion will add very little to what states would have spent on Medicaid without health reform,
I would say state opposition to Medicaid expansion is mostly ideological.
